[@ehsaanschannel2449]

Thanks buddy. My ac was blowing hot air and I thought it was the compressor but after watching your video I changed the relay and now it’s blowing cold air ❄️ (04 Corolla)

[@GEARMOAUTO]

Hell ya.

[@bradyburns2672]

Same homie

[@mrjc12]

YOU ARE A FRIGGING GOD!!! 50 bucks down the drain on that stupid refrigerant. Thank you very much, now I just need to replace the horn fuse. You will be receiving a donation sir.

[@GEARMOAUTO]

Thanks for the support buddy. Happy 🥶 ❄️❄️❄️❄️

[@mrjc12]

@@GEARMOAUTO happy frozen to you too!!! AC working great!!

[@George_S.G]

this is amazing fallow this video and you are going to find the problem no question ask, thank you my friend we need people like you here in youtube!!!!!

[@nvomund]

Dude, your video helped me get my A/C back up and running for $15. Can't thank you enough!

[@DANIELSAM329]

nvomund how you did it?

[@nvomund]

@@DANIELSAM329, I followed the instructions in the video and discovered I had a bad AC compressor relay. Bought a new relay from O'Reilly's for $15 and had the AC back up and running.

[@CarlMarvin]

Great video! I was starting the troubleshooting problem and step 1 was it. Love the idea of switching in the horn relay. Worked a treat! Thanks for saving me lots of time and potentially money!

[@mattyvoodoo]

This worked! Just saved me $500 in car repairs. Seriously, this was simple, fast and changed my f**king life. IT WORKED!

[@GEARMOAUTO]

Thanks bro. Glad to help.

[@robertmckague8857]

Great video . Easy to understand and simple but yet very informative

[@shaunadeguire6655]

For over two years, I have been without A/C because I was quoted at a $2,000 fix at a mechanics shop. After following these clear simple instructions in your video, I tried the AC relay switch and now I have A/C!! For less than $25 bucks! Thank you more than words!

[@mohammedalmukhtar8949]

OMG! 2 years without AC? so sorry for that

[@muhammadusman5351]

thanks, buddy it works.....in addition to that I wanna add something. I didn't even have to spend 1 penny. I put my horn relay in AC spot and my AC was working fine, however, my friend told me to shake the malfunctioning AC relay and gently hit on the floor/wall 3,4 times and then put it back on AC socket...hell yaaaaaaaaaaaaa mine worked and I didn't even have to spend a single penny. thanks man and God bless you all. Asalamoalikum

[@MrSenorhappy]

Thank you for this great video. Ok so I swapped the relay with the horn one and nothing. Mu horn works with either relay. I did the bypass on the pressure switch and the radiator fan kicks on but the clutch on the compressor doesn't kick on. So whats next?

[@solomonsgtjustinl9724]

So what did you use to short the connector terminals?

[@ryanm2084]

Thanks for the tip. I did it this morning and it fixed it 👍

[@superswagproud7189]

My moms corolla ac doesnt work so i showed her this video (it actually worked)

[@dougtheeliminator1077]

My mother owns a 2004 Corolla. She recently told me her A/C stopped working in the car. After doing both of your tests (relay swap and jumped the freon monitor switch), I noticed that she accidentally must have hit the push button A/C switch on the dash board, which disengages the compressor for fan only. Problem solved. LOL!!!!

[@Ravoof]

The problem I have - Hot air in between normal cold air. What could be the problem? Any suggestions. I did change/refill refrigerant.

[@davepurnell8269]

Bad relay, thanks for the tip!!

[@blantonator]

nice. just worked for me!

[@AzChris-uz4mk]

You the man. It worked

[@Wanhope2]

You are a god damn miracle worker

[@Fauconperche]

I don’t understand ur « bypass by these terminals » witch wire you use?

[@ZexionRox97]

This video saved me - 10/10 please make sure you do this, so easy and saved me much trouble

[@johnwallace9342]

The "relay test" worked for me fixing my daughter's 2003 Corolla. AC clutch would not engage, and I was perplexed on what was the problem. I was about to pull the compressor out tomorrow to check to loose wires, etc. You saved the day. I'm sure if my daughter had taken her car to a shop or Toyota dealership, they would have told her she had a bad compressor due to the age of the vehicle, and charged her $500 to $600 to replace it, then when it still didn't work, they would do a little troubleshooting and find out it was just a bad relay! Thanks for the clear and simple step-by-step diagnostic video. Keep up the good work!

[@veronicaserrano9301]

Thank you so much for this! Never would’ve thought of this. You saved me so much money

[@corey6393]

Did you ever do a video on replacing the compressor? If so I could not find it in your list. My 08 Matrix is having A/C issues, and though a bunch of troubleshooting is does appear to be a bad compressor. I'm sure I could figure it out, but you do a great job with these videos and I like to see the process before diving in.

[@humid-rb7rt]

Man you nailed it and thanks!!! I changed the fuse and voila cold air! Thank you my friend and blessings to you.

[@johnofalltrades9581]

Great Tips right there! These A/C Systems on economical cars are so simple that there are only a few basic things that can go wrong. You have provided a great easy check for anyone to do. Even me, owning many cars and I work on all of them found this useful. It helps to get a simple, specific tip that worked. My Relay just needed to be wiggled to clean off the connection after years of use.

[@MyCatTookOverMyChannel]

Replaced the raidator and ac compressor and the relay, car gets cold for a couple days then gets hot. Does this sound like a leak or which fuse under the steering wheel needs replaced same make and model

[@pacoczs926]

How did u bypass the switch? U just showed two cables. Do u have to connect it to something else? 🤔

[@josephrhone7990]

THANKS MAN!! i did what you said and switched the horn with the other relay, BAM! the compressor clutch started spinning and i have ac.

[@dudeinoakland]

There is also a fuse in the passenger compartment that could be checked before jumping. Driver side foot well. but your mentioned it.... Very informative thanks

On my toyota corolla 2004, compressor is working fine but ac colds and warm repeatedly while driving

[@MrJimckorn]

244000 miles on my Corolla and it was the relay. Thank you!!!!

[@ansar311]

My compressor in the car runs but still blows hot air. Is my car low on refrigerant?

[@GEARMOAUTO]

Probably

[@stuzeviews]

Not sure if my compressor working on 2003 1.4 corrolla but note that the Demist switch light doesn't come on, and the fan does not change speed when the rocker switch pressed on mode "Demist". Could this be the relay or something else?

[@genohall3180]

Ok what if u still have refrigerant still in the ac lines I have no air blows hot air and I'm try to put a new AC compressor on my 05 Toyota Corolla CE

[@IZZY3201]

Amazing, i tested my magnetic clutch relay and it clicked when power was applied but wasnt working. I used your tip to switch with horn relay and it worked. Thanks👍👍👍

[@edwardlatt7383]

UGH.. I wish i would have seen this video before I went shopping. Bought the coolant with guage ( ~$30) checked line with guage and system was fully charged.. saw this video and it was the relay.. thanks dude.. great vid

[@CaptainDavidJones]

Bro i was just given an 03 corolla le today for free did exactly this... BOOM working air! Thank you!

[@Rougefox14]

I cannot believe the relay was the issue. I was prepared to spend $1000 to replace my compressor. Thank you so much for this!!

[@erickboemio6424]

Yeah some times mechanics take advantage of one little thing and they get what they want 🤑🤑,but Fortunately I found your video man this is incredible I did exactly what you did , now im enjoying when I turn on the ac ❄❄ thanks again.

[@jimsloane7270]

That was so informative I literally walked in, you tubed, walked out swapped horn relay and bingo we have ac. Of course I was messing with electrical system today and thought that I had unplugged something but alas the relay shit the bed. Thankyou

[@HowardTibsTheThird]

You are awesome! It was my relay! I swapped them and now horn doesn’t honk and AC compressor kicks on! Saved me a bunch of running around and best of all, I’ll be cool on this hot July 4th!!

[@lukki7ster]

im gonna be so mad i suffered for 3 years in this car with no AC if this works lol. But will be very greatful for this vid :)

[@Oluwasedago]

This really saved me a lot of money. The technician I called was already asking to change the radiator, compressor, expansion valve. I did this and found the issue. I was low on refiedgerant. It looks llike I have a leakage so I will look into that. Thanks very much.

[@pmlonline]

In 2001 the inside fuses are behind the left side storage compartment. It's a small compartment. After it opens all the way just pull a bit and it will snap out, and presto, lots of fuses right before your eyes.

[@andrearichman]

The relay, go figure, exactly what was wrong. Seemed too simple, I hadn't even checked it, thanks!

[@FocalEvergreen]

Literally just saved me from buying a new compressor! Only thing wrong was the relay!

[@grantsvlogs]

Thanks for getting to the point lol helped more than other videos! Solved the problem first try

[@davidknibbs9646]

When i turn the AC on the air works,but when the compressor comes on the fan turns on and then thay both turn off a the sametime

[@rimoto2645]

Thank you Gearmo. My relay failed and you helped me fix it before I did something dumb like taking off the compressor.

[@PabloHerrera-ho4nm]

I love you.... u saved my a lot of money i swapped the relays and bam worked like a champ..thank you very much

[@michellecallaway2604]

Thank you so much for this video! The first thing you showed was exactly what was wrong with my ac. So very helpful and I don't have to burn up while driving now:)

[@tammyhurt6648]

I just wanted you to know that i watched ur video went outside switched the relay and my air works i live in Louisana and you are my hero thank you

[@kenningosh2602]

Switched the relay fuse and it worked; so i went and bought a new relay. Thanks for the video, saved me money..

[@isaiahbaker3597]

Thank you!!! The relay swap trick made it work as good as new

[@bertblue9683]

Loved the video, thorough and short and easy to understand. Thank you!

[@TTruthWarrior]

The relay just fixed our AC on our Toyota Corolla... thank you 🙏

[@oxeagles29]

Thanks man, you helped me out. Great video!

[@Not_Your_Regular_News]

Great vid about to check to see if works, great video

[@martinziebell1479]

Thanks man! This was a great way to run diagnostics.

[@aliceroder4586]

This is good...to the point with good info and pics! One question: At 2:38 it shows by-passing switch. Is that a simple loop pigtail?

[@GEARMOAUTO]

Ya its just a simple loop wire. In fact i usually just use a conductive paper clip. Anything really can work thats a conductor. Just dont have it plugged into the connector and let it touch anything eles cause it can short and pop your A/C fuse.

[@eduardoguzman2282]

Hey, I’ve a corolla 05 same engine as you have right there. I already check all what you just said. What I need to know is how can I refill the gas, how much pressure and all what I would need know to refill it.

[@edwardlatt7383]

You can buy a can of AC Pro gas with a guage ( instructions included) for about $30. they even sell em at Walmart.. super easy to do . Guage is reuseable. Corollas take about 19 ounces total, can is 20 ounces.

[@eduardoguzman2282]

edward latt Great, thank you . I’ll do that today.

[@juanandres1767]

Awesome. Thank you very much.

[@totiriel6079]

[@greenfinchgreenfinch3094]

👍👍👍👍👍👍❤️🌿❤️🌿🌿🌿🌿🌿🌿🌿🌿

[@blawsonbl]

04 Toyota just like yours. Relay is good but when I jump the high pressure switch the fans for the rad come on but not the clutch. Only getting 3 volts from wire running to compressor. Any help

[@SgtRandlemen]

blawsonbl sounds like your ac compressor is out of life. I found some cheap ones online for under 150 dollars. I'd replace it yourself so you can save a few hundred bucks, but if you're not mechanically inclined or don't have any tools, you should take it to a shop or have a mobile mechanic do it.

[@blawsonbl]

Zach Hale thanks for the reply! It was the relay. I had to press it really hard Into the holder. I put some dielectric grease on it should help some. Thanks for your help

[@SgtRandlemen]

blawsonbl no problem! Wish it was that simple on my fiances car! Guess I'll be switching the compressor this weekend..

[@blawsonbl]

Zach Hale we got lucky! My luck is normally not that good! Good luck with yours this weekend

[@keyboardkungfu]

Worked. Thanks!

[@brandenmoore2539]

Worked thanks

[@HelloSteph0h]

i cant seem to be able to take out the relay lol i dont want to break it by pulling to hard, what can i do?

[@GEARMOAUTO]

They can be stuborn. Use a pair of pliers but try not to squeez them too hard. But if u break the relay they are only 15 to 20 bucks to replace

[@HelloSteph0h]

Gearmo Auto ok I’ll try that, thank you! I thought I needed Freon on my car and put some and everything is the same and spent $61 for not to work :( so I hope it’s the relay
